Desk accessory support

ABSTRACT

A desk accessory support for use with a desktop has an upper surface, a lower surface and an edge extending between the upper and lower surfaces. The support includes a first abutment for abutting the upper surface, and a second abutment for abutting the lower surface. A connecting structure is configured for connecting the first and second abutments to each other. The first and second abutments and the connecting structure define a substantially U-shaped recess for receiving the edge of the desktop.

TECHNICAL FIELD

The present invention relates to means for supporting a keyboard, a VDU monitor or the like in relation to a desk having an upper surface and an opposed lower surface.

The invention has been developed primarily for use with an office desk or work station and will be described hereinafter with reference to that application. However, it will be appreciated that the invention is not limited to that particular field of use and is also applicable to other work surfaces, storage surfaces or the like.

BACKGROUND ART

Hitherto, the inclusion of a keyboard platform on an office desk has necessitated specific mechanical alterations of that desk (for example a cut out section) to accommodate the linkage mechanism joining the platform to the desk. This is particularly so for linkage mechanisms which allow height adjustment of the keyboard platform. Because of the many configurations and variations required to meet the specific demands of the office and consumer markets it is difficult for manufacturers to conveniently and cost effectively produce the desks and associated keyboard supporting platforms.

The keyboard to be placed on the keyboard platform is generally associated with a computer having a screen which is located on the desk surface. However, the narrow width of most modern desks makes it increasingly difficult, even with the use of known keyboard platforms, to maintain a distance between the screen and the eyes of the operator using a keyboard which meets the internationally recognised optimum of 550 mm. Moreover, once an optimum is achieved, further height or angular adjustment of the screen is generally impracticable, whether it be to share screen information or for operator convenience of comfort. Attempts to provide adjustable monitor supports also suffer from the disadvantage of requiring desk surface modifications. To avoid this it has been proposed to employ a monitor platform attached to the desk via an arm extending from a screw clamp. Such arrangements are often insecure because of the weight of the monitor. Screw clamps cannot be placed at the front edge of the desk because their bulk interferes with the attachment and/or use of a keyboard and renders the desk surface unusable. Attachment of screw clamps at the desk rear or desk side edges tends to damage the desk and to interfere with placement of desks against a wall or screen (if clamped at the rear) or side-by-side (if clamped at the side). In general, monitor supports tend to occupy an excessive desk area or interfere with desk space.

It is an object of the present invention, at least in the preferred embodiment, to overcome or substantially ameliorate one or more of the disadvantages of the prior art.

MODES FOR CARRYING OUT THE INVENTION

Referring to FIG. 1 and FIG. 2, there is shown a keyboard support 1 for a desk 2 having a substantially planar upper surface 3 and an opposed co-extending lower surface 4 having respective straight edges 5 and 6. The edges are joined by a vertical sidewall 7 which extends in a plane and that is substantially normal to the upper and lower surfaces. Support 1 includes a first mounting means in the form of a planar rectangular metal plate 11 which abuts the adjacent upper surface 3. A second mounting means in the form of a second planar metal rectangular plate 12 is connected to plate 11 by way of an intermediate portion 13 and abuts the adjacent lower surface 4. Plates 11 and 12 are substantially parallel and, in combination, maintain support 1 in a predetermined disposition with respect to desk 2. A linkage assembly in the form of a pantographic linkage mechanism 21 extends from a first pair of parallel brackets 22 adjacent plate 12 to a second pair of like brackets 23. A keyboard support platform in the form of a support surface 30 is mounted to brackets 23 to selectively support a keyboard (not shown).

With reference to FIGS. 1 and 2, plates 11 and 12 and connecting portion 13 are preferably integrally formed from a single folded steel plate such that the distance between the opposed plate faces 11, 12 is substantially equal to the distance between desk edges 5 and 6. In other embodiments, opposed faces 11, 12 are disposed slightly further apart and use is made of respective strips of dense resilient foam to facilitate an interference fit between support 1 and desk 2, while also reducing the risk of any point loading.

In other embodiments plates 11 and 12 and connecting portion 13 are integrally constructed from plastics.

Linkage mechanism 21 includes four parallel arms 35 which are arranged in two spaced apart pairs which extend between respective brackets 22 and 23 to allow altitude adjustment of platform 30 with respect to desk 2. As would be appreciated by those skilled in the art other linkage mechanisms are also suitable. For example, in some embodiments the linkage mechanism allows tilt and/or altitude adjustment of platform 30, while in other embodiments platform 30 is fixed with respect to desk 2.

Linkage arms are connected to brackets 32 at a distance inwardly of connection 13 at the desk edge. Consequently the weight of platform 30 results in a torque being generated which is transmitted by arm 35 to plates 11 and 12. This torque forces the plates into more secure engagement with the respective adjacent surfaces 3 and 4. If an object such as a keyboard is placed on platform 30 it will increase the torque and hence the plates will more securely impinge upon the adjacent desk surfaces. Accordingly, an inherently safe self locking system is provided. For example, if an operator or other person inadvertently applies a load to platform 30, by leaning on it or otherwise, support 1 is further locked to desk 2.

As best shown in FIG. 1, upper and lower surfaces 3 and 4 are L-shaped and define a corner work station for a computer operator.

In the FIGS. 1 and 2 embodiment, plate 11 includes longitudinally extending edges 31 and 32 which are joined by transverse by extending edges 33 and 34. Plate 12 also includes longitudinally extending edges 31 and 32 and transversely extending edges 37 and 38. As shown, edge 38 is disposed intermediate edges 33 and 34 although in other embodiments edge 38 is adjacent to edge 34.

Plate 11 includes a slot 40 which extends longitudinally inwardly from edge 34 and terminates at rounded end 41. Slot 40 allows a cord extending between the keyboard and the associated computer to be discretely passed under plate 12 and then onto surface 3. This results in a more aesthetically pleasing arrangement which is also less likely to hinder the height adjustment of platform 30. In some embodiments slot 40 is large whereby plate 11 is in the form of a frame extending inwardly from the periphery of the plate shown in FIG. 1.

Support 1 is shown in FIG. 1 mounted to the corner of the L-shaped surfaces of desk 2. This is effected by initially manoeuvring edges 34 and 38 to be adjacent edges 7 and 8 respectively. Thereafter, plates 11 and 12 are biased away from each other to separate ends 34 and 38 sufficiently to allow their progression beyond edges 5 and 6. The biased is then removed allowing plates 11 and 12 to co-operatively grip surfaces 3 and 4, and, if required, support 1 further manoeuvred into a desired configuration. Although platform 30 is shown bridging the corner of desk 2, it is equally suitable for mounting along one of the straight edges, that is, with edge 34 maintained substantially parallel to any edge of the desk.

In FIG. 1, platform 30 extends transversely beyond plates 11 and 12 and includes bevelled sides 45 which lie flush with the adjacent sidewall 7. For embodiments of support 1 which are intended for symmetrical mounting in the corner of desk 2, bevelled sides 45 extend at 45° to edge 34. In other embodiments platform 30 transversely coextends with plate 11 and includes straight sides.

Reference is now made to FIG. 3, where corresponding features are denoted by corresponding reference numerals. More particularly, a support 46 is illustrated which includes a plate 12 (second abutment means) having a down turned edge 38 defining a lip 47 for facilitating initial placement of the support on desk 2. Moreover, support 46 includes two parallel spaced apart longitudinally extending tracks 49 disposed between plate 12 and respective brackets 22. The brackets are captively and slidably mounted to the tracks to allow longitudinal progression of platform 30 between an extended and retracted configuration with respect to desk 2. Platform 30 is illustrated in the extended and retracted configurations by unbroken and broken lines respectively. Progression of platform 30 toward the extended and retracted configurations is limited, for example, by bump stops (not shown) adjacent portion 13 and lip 47 respectively. In some embodiments at least one of tracks 49 include a plurality of spaced apart locking formations which are selectively engaged by a complementary formation on the adjacent bracket 22 to effect positive locating of that bracket with respect to the track.

Platform 30, in some embodiments, has a sufficiently large surface area to accommodate, in addition to the keyboard, one or more other input devices such as a mouse, joystick, removable hard drive, tape drive or the like. However, in some circumstances an operator requires additional space to conveniently locate input devices for the computer other than directly on platform 30. This is easily achieved through use of the embodiment of the invention illustrated in FIG. 4 and generally designated as auxiliary platform 52.

Auxiliary platform 52 includes plates 11 and 12 and portion 13, similarly to the other embodiments described above. However, in this case, auxiliary platform 52, is substantially smaller than platform 30 and fixed with respect to plates 11 and 12 by a pair of parallel underlying beams 53. These beams are fixedly attached to plate 12 and convert any torque arising from a load applied to platform 52 into a locking force between plates 11 and 12 and respective adjacent surfaces of desk 2.

In some embodiments platform 52 is mounted to platform 30 rather than desk 2.

Platform 52 is intended to support a mouse 54 or other input device. In this embodiment the upper surface of the platform includes a neoprene layer 55 to facilitate operation of mouse 54.

Platforms 30 and 52 can all be retrofitted to existing desks or other surfaces without any modifications being required. Moreover, platforms 30 and 52 are easily moved for optimum placement by applying a bias to the support surface to counteract the gravitational bias applied by any load carried by that surface.

Platforms 30 and 52 being cantilevered from plate 12 are self-locking and ensures that when a load is applied to the platform surface that the support will be more securely located on the desk.

As support 1 extends beyond sidewall 7 of desk 2 it provides a user with additional desk space and allows that user to comfortably and easily maintain a greater distance between their eyes and the screen.

Reference is now made to FIGS. 5 and 6 which illustrate an alternative support 60, where corresponding features are denoted by corresponding reference numerals. These figures are intended to show the direction the forces acting upon plates 11 and 12 during upward and downward adjustment of platform 30. More particularly, in FIG. 5 platform 30 is in the raised configuration and a downward force represented by arrow 61 is applied to move the platform to a reduced height with respect to desk 3. This results in the generation of forces represented by arrows 62 and 63 respectively on the front and rear edges of plates 11 and 12. These forces act to further lock support 60 to desk 3. When platform 30 is in the lowered configuration, as shown in FIG. 6, it is necessary to apply an upward force, represented by arrow 65 to more the platform surface to a higher position with respect to desk 3. With the application of force 65, two forces are generated, represented by arrows 66 and 67, respectively, which act on the front and rear of plates 12 and 11. Again, locking action is effected.

The application of either of forces 61 or 65 has the desired effect of locking support 60 to desk 3, notwithstanding the opposed nature of these forces.

Reference is now made to FIG. 7 which is a perspective view of two plates 75 and 76 which form part of a keyboard support according to the invention. For the purposes of clarity the linkage assembly has been omitted, although it will be appreciated that, in use, such an assembly extends from the bottom of plate 76.

Plates 75 and 76 are opposed and include respective flanges 77 and 78 which extend toward the other of the plates. Preferably, each flange extends normally from its respective plate.

Flange 77 includes two spaced apart circular apertures 79 and corresponding nuts 80. In other embodiments nuts 80 are omitted and apertures 79 are threaded.

Flange 78 includes two spaced apart parallel extending slots 81 which, in use overlie apertures 79. Respective bolts 82 are inserted through slots 81 and apertures 79, and threaded into engagement with nuts 80 to maintain flanges 77 and 78 in a fixed spaced apart configuration.

During installation of the keyboard support to a desk, bolts 82 are loosened to allow movement of plates 75 and 76 into engagement with respective opposed surfaces of a desk. Thereafter, bolts 82 are tightened with respect to nuts 80 to securely maintain the plates in the engaged configuration. Accordingly, plates 75 and 76 accommodate a variety of desk thicknesses.

Plate 75 includes a mouse pad 83 in the top right hand corner. This allows a user convenient access to the keyboard, which is located on the support platform (not shown) and a mouse located on pad 83.

An alternative arrangement is illustrated in FIG. 8 where, again, the linkage assembly has been omitted for clarity purposes. More particularly, two spaced apart, substantially parallel plates 85 and 86 are integrally formed and are joined by an intermediate curved resilient portion 87. Portion 87 flexes to allow a greater separation between plates 85 and 86, thereby accommodating a range of desk thicknesses, while resiliently biasing plates 85 and 86 to co-operatively grip the desktop (not shown).

An alternative embodiment keyboard support 90 is illustrated in FIG. 9. Support 90 is similar to support 60, as illustrated in FIG. 6, and corresponding features are denoted by corresponding reference numerals. The plates 11 and 12 of the FIG. 9 embodiment are spaced slightly further apart than those shown on FIG. 6 to provide a small gap between the plates and the respective adjacent surfaces of desk 3.

Plate 11 and plate 12 both include spaced apart rubber feet 91 and 92 which are respectively disposed at the front and rear of those plates. When a downward load is applied to platform 30 feet 91 and 92 are biased into gripping engagement with the adjacent desk surfaces.

Plate 11 also includes a rearwardly disposed spherical roller 93 which is engaged with the top surface of desk 3 when an upwardly directed force is exerted upon platform 30. Such an upwardly directed force will also remove feet 91 and 92 from gripping engagement with the desk surfaces. Accordingly, movement of support 90 is facilitated.

The FIG. 9 embodiment of the invention is intended for mounting to the straight edge of a desk and for subsequent transverse movement along that edge. Preferably, therefore, desk 3 includes a guide in the form of a transversely extending track 94 which overlaps with the rear of plate 12 to facilitate a smooth progression. Track 94 is maintained against desk 3 by way of a plurality of spaced apart screws 95.

Support 90 is easily transversely progressed by a user who simply needs apply an upwardly directed force to platform 30 to overcome the gripping engagement of feet 91 and 92. Support 90 is then progressed transversely, as required, and the upwardly directed force is removed. Platform 90 is then biased downwardly under the influence of gravity and from any resilience between plates 11 and 12 whereby feet 91 and 92 are again biased into gripping engagement with desk 3.

In another embodiment plate 12 includes formations for selectively engaging with a plurality of corresponding transversely spaced apart formations on the lower surface of desk 3. The interengagement between the formations effecting an even more positive engagement between the desk and support. When an upwardly directed force is applied to the platform the rear edge of plate 12 is progressed downwardly such that the formations are disengaged and either transverse and/or longitudinal movement of the support relative to the desk can occur.

With reference to FIG. 10 there is shown an embodiment similar to that of FIG. 1 but wherein a second load bearing platform 100 (in this case adapted to support a monitor) is mounted to first abutment means 11 (the upper plate) by means of a mounting post 102 spaced inwardly from edge connection 13. Desirably mounting post 102 is provided with telescopic, airlift, or other height adjustment and may also be provided with swivel adjustment.

FIG. 11 shows the embodiment of FIG. 10 when supporting a monitor on platform 100, a keyboard on platform 30 and a mouse on upper plate 11.

FIG. 12 shows an embodiment similar to that of FIG. 10 but wherein keyboard support platform 30 is provided with a wrist support 103.

FIG. 13 shows an embodiment wherein a monitor platform 100 is supported by a support pillar 102 from upper plate 11 of support means 1. As shown in FIG. 13 in this embodiment no separate support platform is provided for a keyboard. Instead, as is shown in FIG. 14, upper plate 11 may be provided with a wrist support 103 and the keyboard may be emplaced upon upper plate 11.

FIG. 15 shows a further embodiment similar to that of FIG. 14 but wherein mounting pillar 102 is provided with a laterally extending auxiliary platform 101 whereby a mouse may be supported. It will be appreciated that the embodiments of FIGS. 13, 14 and 15 share the same stability as embodiments earlier described in that the loads in each case tend to improve the grip between the support means and the desk.

FIG. 16 shows an embodiment in which a basket 104 and a task light 106 are supported via a pillar 102 from upper plate 11. It will be understood that in each case pillar 102 may be made of adjustable length and horizontal support arms may be adjustable in height and radial direction from the pillar.

FIG. 17 shows an embodiment wherein a monitor support platform 100 is supported by a column 102 from a base plate 105 and wherein as shown in FIG. 18 base plate 105 is clamped onto a desk top by means of support 1 engaging base plate 105 between upper plate 11 and the desk top.

FIG. 19 illustrates an alternative embodiment to those shown in FIGS. 7 and 8. The embodiment in FIG. 19 includes an upper plate 85 integrally connected to a lower bent plate 86 via an intermediate portion 110. The bent plate 86 includes a portion 86 a disposed in a direction away from the upper plate 85, and a portion 86 b disposed in a direction towards upper plate 85. Plates 85 and 86 are resiliently biased in a direction towards each other, and advantageously this embodiment will allow the desk accessory support 114 to be used in respect of the desk tops (not shown) of different thicknesses. Preferably rubber pads 111 are provided on the upper surface of the lower plate 86 in the vicinity of where portion 86 a meets 86 b which provides protection to the lower edge of a desk top (not shown) when the accessory support is applied to a desktop where the desk thickness is greater than the height of the intermediate portion 110.

The embodiment of the desk accessory support 115 in FIG. 20 is an alternative embodiment to the embodiment illustrated in FIG. 8. The numeric references in FIG. 20 which are also in FIG. 8 refer to the same features in both illustrations. However, the support 115 in FIG. 20 includes an intermediate curved resilient portion 87 formed in a manner to provide a raised formation with respect to upper plate 85 which in use provides a wrist rest for a user operating for example a computer keyboard 112 which has been placed on the upper plate 85.

Advantageously the wrist rest feature 87 is integrated with the upper plate 85 and lower plate 86 of the support 115. Finger 113 is a schematic representation of human fingers which illustrates the intermediate portion/wrist rest support 87 for the purposes of providing physical support to a human hand.

The embodiment of the accessory support 116 shown in FIG. 21 is an alternative embodiment to that illustrated in FIG. 20. The support 116 includes a lower plate 86 bent into 3 portions 86 c, 86 d and 86 e. Lower plate 86 is provided with a lip portion 86 d to assist the location of the accessory support 116 on a desk top. The bent portion 86 c allows the desk accessory support 116 to be applied to thinner desk tops while maintaining the same size wrist rest support 87 for example when compared to the embodiment illustrated in FIG. 20.

As will be apparent to those skilled in the art from the teaching hereof features of one embodiment may be combined with those of another and the apparatus may be constructed from any suitable materials and in forms differing from those depicted in the drawings without departing from the scope of the invention herein disclosed.
